MOF-199 consists of copper-based metal clusters and organic linkers. It has octahedral morphology. MOF-5 consists of zinc-based metal clusters and organic linkers that have cubic morphology. Five samples of MOF-199 materials and three samples of MOF-5 that were successfully synthesized using non-surfactant template (fatty alcohols) from our group [1- 2] were analyzed using nitrogen adsorption analysis. The adsorption-desorption isotherms of MOF-199 and MOF-5 exhibited Type I isotherm generally observed for microporous materials suggesting that the material produced in this study are of microporous (pore size less than 1 nm) nature. The surface area of MOF-199 estimated using BET method and Langmuir method were at ca. 30- 1117 m 2 /g and MOF-5 were at ca. 5-105 m 2 /g. The total pore volume obtained at P/P0 = 0.99 for MOF-199 were at ca. 0.05 to 0.49 cm3 /g and MOF-5 were at 0.09 to 0.14 cm3 /g. The average pore widths of MOF-199 were at ca. 0.53 nm to 0.56 nm and MOF-5 were at 0.26 to 0.53nm. The surface area and pore volume of the materials decreased with longer straight chain fatty alcohol possibility due to mobility of the long carbon chain.||URI:||http://dspace.uniten.edu.my/jspui/handle/123456789/10232|
